  • Applications

    Dotriacont-1-ene (CAS 18435-55-7) is a long-chain alpha-olefin primarily used as a non-polar hydrocarbon feedstock and processing aid in industrial formulations. In industry, it serves as a base oil and a viscosity-modifier in lubricants and greases; as a waxy component in coatings, polishes, and candle formulations to improve hardness and gloss; as a feedstock or intermediate for the production of specialty polyolefins and wax-like polymers; and as a diluent or carrier solvent in coatings, inks, and adhesives. In cosmetics and personal care, it may be used as a waxy emollient or texture enhancer, subject to formulation requirements and regulatory limits.
